To jump onto your comment as a current Spanish learner, dreaming Spanish is pretty good. Language Transfer however is, in my opinion, the beat single tool for learning Spanish.

I think it is best coupled with some other methods, like dreaming Spanish, but I have learnt more from Language Transfer than anywhere else.

Obligatory never use Duolingo, it is fucking trash!

I will always upvote technology connections, I have watched so many videos of his about things I would have thought i couldn’t care less about and enjoyed them all!
